Problem
HMA pavements (P-401 mixes) are designed to last 20 years, and this runway pavement was failing after 3 years.
Solution
Contractor applied a double application of GSB-78®to add high-performance residual asphalt to the HMA surface binder to hold the HMA aggregate in place and mitigate raveling and FOD.
Problem

Solution
Contractor applied a double application of GSB-78®to add high-performance residual asphalt to the HMA surface binder to hold the HMA aggregate in place and mitigate raveling and FOD.
Two years after application, these photos show that the HMA aggregate is still locked down and FOD is mitigated.
The close-up photo on the left shows the GSB-78® and the aggregate applied with it (white) still working on the surface.
The photo on the right shows the amount of high-performance residual asphalt (compared to "Problem" photos) that is in the voids to seal and lock the HMA aggregate in place.
